SpaceWire (ECSS-E-ST-50-12C) and RMAP (ECSS-E-ST-50-52C)
regenerate EverParse C files with wire 0.9.0
Wire_3d now generates ExternalTypedefs.h, ExternalAPI.h, Wrapper,
and Fields files for schemas using WireCtx. Bitfield padding is
fixed so .3d structs match the OCaml codec wire_size. Test.c passes
NULL for the WIRECTX parameter and links per-schema Field stubs.
Affected: ax25, cfdp, fsr, ltp, mbr, pid1, pus, rpmsg, sdls,
spacefibre, squashfs, tcpcl, udpcl, spacewire, and others via @gen.
